Dozens of fighter jets from the Royal Air Force and US Air Force have taken part in a joint training exercise in the UK.
Twenty RAF Typhoons, from RAF Lossiemouth and RAF Coningsby, and 16 F-15s took part in Exercise Point Black.
Other aircraft, including two F-35Bs from RAF Marham, were also involved.
Most of the training was carried out over the North Sea, the RAF said in a statement.
The exercise is usually held quarterly but was put on hold because of the coronavirus outbreak.
It involved personnel based at 10 different locations spread across the UK.
Captain Nathan Hartoin, an F-15 pilot with USAF's 493rd Fighter Squadron based at RAF Lakenheath, said: “[Exercise] Point Blank is instrumental in showing our bilateral resolve to continued operations during these restrictive times.
“The exercise was a resounding success in providing key data points moving forward in being a more agile and lethal combat force.”
The RAF said the exercise practised a number of skills, including Combat Search and Research and the "Destructive Suppression of Enemy Defences".
